Rejection (Rav Acha bar Yakov): This is no proof that R. Zeira retracted. Perhaps he asked according to Rava, even though R. Zeira himself disagrees! (R. Zeira holds that the animal is Kosher (Rashi; Tosfos - Tereifah) no matter where the wound is.)

(Rav Acha bar Yakov): We may derive from Reish Lakish's law that a Yisrael may eat intestines, but a Nochri may not;

This is because for a Yisrael, the Shechitah is necessary to permit the animal;

Shechitah is not needed for a Nochri. It depends only on whether the animal is dead. (Once the Veshet is cut, we view the intestines as if they were removed). Therefore, for him, the intestines are forbidden, like Ever Min ha'Chai (a limb from a living animal), even after the animal later dies.

(Rav Papa): I thought to ask that that we never find something permitted to a Yisrael and forbidden to a Nochri!

I did not ask, for Rav Acha gave a good reason why this is an exception.

Question (Beraisa): There is a way to eat meat taken from an animal before it died. After Shechitah, cut a piece from the place of Shechitah, salt it well and rinse it well. It is permitted after the animal dies, to Yisraelim and Nochrim. (This is unlike Rav Acha, who says that since Shechitah does not apply to Nochrim, it is Ever Min ha'Chai for them.)

This Beraisa supports Rav Idi;

(Rav Idi bar Avin): It is very healthy to eat meat taken from an animal before it died. One cuts a piece from the place of Shechitah, and salts and rinses it well. After the animal dies it is permitted to Yisraelim and Nochrim.

(Mishnah): If one slaughtered a Behemah, Chayah or bird, and no blood came out, it may be eaten with Tamei hands, since the meat was not Huchshar (no liquid come upon it);

R. Shimon says, Shechitah is Machshir the meat.

(Gemara) Question: This implies that if blood came out, it may not be eaten with Tamei hands. Why is this?

Tamei hands are only a Sheni l'Tumah (second-degree Tumah). They would not be Metamei the meat, for Chulin cannot become a Shelishi l'Tumah!

Question: What is the source that the Mishnah discusses Chulin meat?

Answer #1: The Mishnah includes Chayos, which cannot be Korbanos.

Answer #2: Regarding Kodshim, we would not say they are Kosher if no blood came out. We must put the blood on the Mizbe'ach!

Answer #3: Regarding Kodshim, even if blood came out, it is not Machshir;

(R. Chiya bar Aba): "You will spill (the blood) on the ground like water" teaches that only blood that is spilled like water is Machshir. (This excludes blood of Kodshim, which is collected and thrown on the Mizbe'ach.)

Answer #4: Regarding Kodshim, Chibas ha'Kodesh (a stringency of Kodshim) is Machshir the meat without any liquid.

Answer #1 (Rav Nachman): The Mishnah discusses Chulin meat bought with money of Ma'aser Sheni. The Tana argues with R. Meir.

(Mishnah - R. Meir): Anyone who must immerse mid'Rabanan:

If he touches Kodshim, it becomes Tamei. (If it touches other Kodshim, it disqualifies them). If he touches Terumah, it is Pasul. (It is Tamei, but it cannot disqualify other Terumah). Ma'aser Sheni is permitted to him;

Chachamim say, Ma'aser Sheni is forbidden to him.

Objection (Rav Simi bar Ashi): Chachamim forbid him to eat Ma'aser Sheni. They do not say that he may not touch it!

The Mishnah says that the meat may be eaten with (i.e. using) Tamei hands. The case is, one with Tamei hands feeds it to a Tahor person! (Even Chachamim would permit this regarding Ma'aser Sheni, even if it was Huchshar.)

Answer #2 (Rav Papa): The Mishnah discusses hands that are a Rishon (first degree) l'Tumah, according to R. Shimon ben Elazar.

(Beraisa): Hands are never a Rishon (l'Tumah) regarding Chulin;

R. Shimon ben Elazar says, they can be a Rishon regarding Chulin, and a Sheni regarding Terumah.

Question: It cannot be that they become a Rishon regarding Chulin, but not regarding Terumah!

Answer: He means that they can become a Rishon even regarding Chulin. They can become a Sheni regarding Terumah, but not for Chulin.

Question: Can hands really become Rishon l'Tumah?

Answer: Yes!

(Beraisa - R. Akiva): If one entered his hands into a house stricken with Tzara'as, they become a Rishon;

Chachamim say, they become a Sheni.

All agree that partially entering is not considered entering. R. Akiva decrees that the hands are like the body would be if (the majority of) the body entered. Chachamim decree that his hands become like regular unguarded hands.

Question: Why didn't Rav Papa say that the Mishnah is R. Akiva?

Answer: R. Akiva said that they are a Rishon only regarding Terumah. perhaps he does not say so regarding Chulin.

Question: Even if R. Akiva says that they are a Sheni only regarding Chulin, he holds that they are Metamei the meat, for he holds that Chulin can become a Shelishi!

(Mishnah): On that day (that R. Eliezer ben Azaryah was appointed Nasi), R. Akiva expounded "any earthenware Kli... Yitma (food inside becomes Tamei)".

It does not say 'Tamei', rather "Yitma", to show that a loaf inside, which is a Sheni, can Metamei other food (make a Shelishi).

Answer: Perhaps he said so only regarding Tum'ah mid'Oraisa, but not for Tum'ah mid'Rabanan.

Answer #3 (R. Elazar): The Mishnah discusses Chulin Al Taharas (i.e. that one guards from Tum'ah like) Kodesh. It is unlike R. Yehoshua;

(Mishnah - R. Eliezer): If one eats food that is a Rishon, Sheni or Shelishi l'Tumah, he becomes Tamei like the food he ate;

R. Yehoshua says, if he ate a Rishon or Sheni, he becomes a Sheni. If he ate a Shelishi, he becomes a Sheni regarding Kodesh, but not regarding Terumah.

The Shelishi he ate is Chulin Al Taharas Terumah.

Inference: R. Yehoshua discusses Chulin Al Taharas Terumah, but not Chulin Al Taharas Kodesh, for the latter cannot become a Shelishi.
